Atlas Noctis · English pages
What is told, and the truth beneath it
An atlas of folklore that states, entry by entry, how well each belief is actually documented — and says so out loud when the answer is «badly», or «not at all».
Atlas Noctis is written in Italian. It holds 127 entries — Italian creatures and rites first, then the rest of the world — eighteen source checks, and a handful of longer essays. Every entry carries a grade that says what kind of evidence stands behind it, and every entry that rests on nothing says so in the first line rather than the last.
These English pages are a small selection, not a mirror. Translating the whole atlas well would take longer than writing it did, and a bad translation of a text whose only authority is precision would be worse than no translation. So what you find here is the material that is worth reading whatever language you think in, starting with the one below.
In 1786 a British military engineer wrote that the Irish worshipped a god of the dead called Saman. That god appears in no Irish manuscript. Two and a half centuries later it is still the opening line of almost everything written about Halloween. The essay follows the chain of attributions link by link — Vallancey 1786, Keating c. 1634, Rhŷs 1886, Frazer's conditionals — and ends with a chronology of what is attested, including the first printed «trick or treat»: 1 November 1917, in a newspaper in Ontario, ten years earlier than the date usually given.
The four grades
A — documented Historical ethnographic collections, dialect dictionaries, trial records, peer-reviewed studies. Material somebody recorded while the belief was still alive.
B — partly documented The core is real, but the record is late or reaches us through an author's pen. True, with an intermediary in the way.
C — weakly documented Findable almost only on blogs and tourist sites. It stays in the atlas, flagged: knowing that a tradition was born the day before yesterday is worth as much as knowing an old one.
L — authorial invention Not folklore. Literature, with an author, a month of writing and a magazine issue number. It lives in a section of its own, and stays there.
Three rules, and one answer
Every entry declares its grade. A documented pseudo-tradition is ethnographic material just as much as a genuine one. Lying about its age is not.
The evidence is not the interpretation. That water-spirits were Celtic deities demonised by Christianity is a reading, and it circulates everywhere as a fact. Saying so takes nothing away from the story. It takes something away from whoever sells it as an artefact.
The reality check is not a verdict. Where a documented phenomenon sits behind the tale — sleep paralysis, tuberculosis, a bird of prey mistaken for something else — it appears in a box at the foot of the entry, distinguishing what is settled from what is merely the prevailing hypothesis. It is neither debunking nor defence: both camps select their evidence the same way, in opposite directions.
«I don't know» is an answer. For some entries I found no early attestation. For others the sources contradict each other on the numbers. It is written in the entry, where anyone can read it.
The longer version of all this is on the Method page, together with what I will not do and why I do not sign with my own name.
The atlas itself — the 127 entries, the maps of Italy and of the world, the source checks, the plates — is in Italian, at atlasnoctis.com. The entries are short and heavily linked, and a browser's translation will carry you through them; the grades, the dates and the citations survive translation intact, which is most of what matters here.
